The photographer said she regularly takes photos of older couples "as a way to inspire young couples." She decided to reach out to the sisters, who live in Ibiraçu, Brazil, hoping they'd participate in a photo shoot to mark their milestone birthdays.

They immediately agreed.

Lima, 28, said the two-hour photo shoot on Monday included hair styling, makeup application and pink and blue matching dresses. She added that the two sisters "were all excited."

"They did everything I asked and did not complain about tiredness," the photographer said, noting that both were "very happy and satisfied" with the finished photo shoot.
